Abstract
The colorimetrical method of Shaw of estimating adrenaline (or epine-phrine) gives to the venous blood from the suprarenal gland in the dog (anesthetized with ether) a similar or somewhat larger amount of epine-phrine (1-2 times), compared with the rabbit intestine segment method, while the relation is quite reverse in the case with the suprarenalmedullary tissue of the same species of animal. The amount of epinephrine deter-minable there by the intestine segment method doubles that of the Shaw test.
